IMPROVEMENT IN MAKING WOODEN BOXES.

Specification forming part of Letters Patent No. 211,130, dated January7, 1879; application filed September 3, 1878.

To all whom it may concern:

Be it known that I, GILBERT W. BRADLEY, of Sunderland, in the county ofBennington and State of Vermont, have invented a new and Improved Modeof MakingWooden Boxes, of which the following is a specification:

The invention relates to a new process of forming wooden boxes, whichwill first be described in connection with all that is neces sary to afull understanding thereof, and then pointed out in the claim.

In making the boxes, strips of veneer are out of the required length andbreadth, which are then passed through a series of sets of rolls ofthree to a set. These rolls are similar to the rolls of a tin-pipeformer, except in the second set the back roll is placed higher. Eachsucceeding set of rolls is arranged to give an increased pressure, thethird or last set giving a heavy pressure, and forming the cylinder veryneatly. By this operation the wood is compressed and smoothed, so thatthe use of sand-wheels or sand-paper is unnecessary. The ends of theveneer bands are then da1npened, overlapped, and sewed, and the bodies.thus formed are placed upon the drying apparatus.

The tops and bottoms of the boxes are exactly alike, and are each formedas follows:

The material is first cut into a circle of the proper size by acylinder-saw, and is then cut with a smaller cylinder-saw to the properdepth to form the flanges or rims. The molding is then out upon the edgeof the-circle, and the portion within the inner saw-cut is taken out,and the bottom and top are ready to receive the body. flange and anarrow ring of the bottom are coated with glue, and the lower edge andthe GILBERT W.
